WindowServer: Fix incorrect "window left" event after button drag

Browse source 
This fixes an issue where we'd send a "cursor has left the window"
message incorrectly to the client after a button was clicked and the
user moved the cursor a little without releasing the button.

The issue was that we didn't update the 'hovered_window' out param
in mouse event processing in the case where we had an active input
window set.
